It has been common practice to use various constructions and materialsto take up. dampen or absorb shocks, jolts and vibrations'in' many types0! machines and vehicles. springs, rubber,

.air cushions and liquid columnsare among the means used in variousarrangements and dispositions. The particular machine or equipment inwhich they are used is an important factor in de termining whichmaterial shall be chosen and how it shall be arranged orvdisposed.

' In order to more clearly disclose the construction, arrangement anddisposition of the invention reierence should behad to the accompanyingdrawing forming part 0! the present application. r

Throughout the several figures oi the drawing like rererence charactersde i n te the same parts in the several views.

In the drawing-- Pig. 1 is a side elevation, assembled;'

I'ig. 2 is a side elevation partly broken away to show details; and

Fi 3 is an end view of Fig. 1.

Referring to the drawing in detail, 1 indicates the cradle of usualform, adapted to receive and support a dynamotor or other machinesubject to considerable vibration. This cradle is proiactured and usedby or for theGovernment ior let tothe interior of the dynamotor. Guide Iis constructedand disposed to cooperate with flange I through aninterposedflshock and vibradon' dampening member. To that end, it has anout-- wardLvrolled curved flange I extending'about its e This time isapproximately plementary to flange "I. *In assembled'positiomas-ln'l'ig.2; thguide land flanges 1 and I IJG'IO spaced that thegynth'etic'rubb'er' or rubber snub- ,bing ring II, seated on I, willcontact flange I at about the point. where I merges into cover I.

The decreasing diameter of l, pinches iI between I and 1 in any upwardmovement of the dynamotor and cradle relative to base I and'c'over I.

By the. arrangement hereabove set forth the blocks I provide adequatecompression shock absorbing elements in movements of the cradle I towardthe plates I while the ring il provides an adequate compression shockabsorbing element in movements oi the connection I-I toward the flange lof base cover I. Ineflect, there is a com- Med with footings 2 atopposite ends and opposecured to and extending upwardly from the cover Iof the base I. In the instance shown, the base is a case or boxcontaining the various conductors and binding posts. The top of thiscase is provided with an opening I about which extends an upwardly andinwardly extending or irusto-conical flange I through which the wiringpasses from the base I to the dynamotor. A tubular guide I carried bythe under side of the v plete cushion between the dynamotor and its baseor support, capable or completely absorbing all shocks and vibrationsbetween them.

These same elements I and iI also provide complete electrical insulationbetween the parts.

The material preferred for the compression members I and member II issynthetic rubber. By a series of severe tests, it has beensatisfactorily proven that in assembly such as here disclosed, syntheticrubber is eflicient and .will give the desired results whereas variousother cushioning media are not so eilicient or satisfactory.- It isthought that the construction, operation and use of the invention willbe clear from preceding detailed description.

Havlngthus disclosed my invention, what I claim and desire to protect byLetters Patent is:

1. An anti-vibration mounting of the character described comprising abase provided with an opening surrounded by a'iiange, a cradle adaptedto receive and support a machine provided with a centrally disposeddownwardly directed tubular member adapted to be extended through saidbase opening and provided with a flange complementary to said baseopening flange. compression anti-vibration members interposed betweensaid cradle and said base and an antivibration member interposed betweensaid flanges. 2. An anti-vibration mounting of the character describedcomprising a base provided with an opening surrounded by a flange, acradle adapted to receive and support a machine and 'an anti-vibrationmember interposed between said flanges and positioned to be wedgedbetween said flanges by relative approaching movement of said flanges.

3. In combination in an anti-vibration mounting of the characterdescribed, a base member provided with an opening thcrethroughsurrounded by an inwardly and upwardly directed flange, a cradledisposed on said base and provided with a downwardly extending tubularmember adapted to be passed through said opening and provided with aflange complementary to the flange about said opening, and ananti-vibration member confined between said flanges.

4. In combination in an anti-vibration mounting of the characterdescribed, a base member provided with an opening therethroughsurrounded by an inwardly and upwardly curved flange, a cradle disposedon said base and prosided with a downwardly extending tubular memberadapted to be passed through said opening and provided with a.downwardly and outwardiy curved flange approximately complementary tothe aforesaid flange, and an anti-vibration member of greater diameterthan the opening through said bas and conflned between said flanges.

5. An anti-vibration mounting of the character described comprising abase provided with an opening therethrough surrounded by an upwardly andinwardly directed flange, a support provided with a tubular memberextending through said opening and provided with a downwardly andoutwardly directed flange substantially complementary to and spaced fromthe flrst mentioned flange and an anti-vibration member interposedbetween said flanges and positioned to be wedged between said flanges byrelative appreaching movement or said flanges.

6. An anti-vibration mounting of the character described comprising abase provided with an opening therethrough surrounded by an upwardly andinwardly directed flange, a support provided with a tubular memberextending through said opening and provided with a downwardly andoutwardly directed flange substantially complementary to and spaced fromthe flrst mentioned flange and a rubber ring interposed between saidflanges and positioned to be wedged between said flanges by relativeapproaching movement of said flames.
